Illinois also has a large mining industry that produces products such as clay, gravel, limestone, sand, silica, and fluorspar. With all of the mining and agriculture keeping the rural parts of Illinois afloat the state has a service led economy which is centered in the power house city of Chicago (2010). Chicago currently ranks second to Los Angeles in manufacturing products which include machinery, construction equipment, food processing, pharmaceuticals, electrical equipment, printed material, and book and newspaper publishing. Back in the early nineteenth century, growth of railroads lead to Chicago becoming one of the most productive cities in the Midwest which made it a hub for transportation (1998). Illinois is home to one of the country's few powerhouse cities that have everything you could possibly look for with Chicago. Chicago is the third most populous city in the United States with 2.7 million current citizens. Chicago boasts some of the largest in our country when it comes to buildings, airports, and rail systems (1998). Standing at 108 stories and 1,451 feet, the Sears tower was the tallest building in the world at one time and is currently the tallest in the United States. Boarding nearly 32 million passengers in 2012, the O'Hare International Airport is the second largest airport in the US. The "L " train system is the largest commuter rail system in the United States which gives users access to the suburbs (Chicago's Landmarks). The city of Chicago consists of many different neighborhoods that are home to many different cultures and ethnicities which make Chicago and its surrounding suburbs one of the most diverse areas in the United States (1998).
Chicago's diversity has been what many consider a major influence to the city's music scene. When people from down south moved to Chicago in "The Great Migration " they combined their traditional southern jazz with the culture of the city and produced a style known as Chicago Blues.
